GOLF

Application filed September This invention relates to an improved golf club which provides a detachable head or series of heads for the shaft whereby the same shaft can be used for various heads.

The invention also relates to a club in which the connection between the shaft and the head is constructed so that the shaft when of hollow metal, as steel, is protected from excess shock at the impact of hitting the ball. This protection is in the form of a cushion, as a rubber ring, which embraces the shaft at the place where the top of the head or rather the shank of the head engages the shaft.

The invention also relates to the locking of the club head in position on the shaft and the storing of the tool for locking and unlocking the head in the top of the shaft.

The invention is also directed to certain details of construction which will be hereinafter more fully described and included in the claims.

The invention is illustrated in the accompan ing drawings in which Figure 1 is a section of a golf club made according to my invention, the shaft of the club being broken away between its two ends. Figure 2 is a section on line 2-2 in Figure 1.

In the drawing the shaft is illustrated at 10, the type shown being of the usual hol- 6 low steel type and the club head is shown at 11 with a shank 12 for attaching it to a shaft. The shaft is provided with a ferrule 13 which ferrule fits tightl on the shaft and is secured thereto usually y hard soldering. The shank 12 of the club head is provided with a screw-threaded recess and is screwed on the ferrule.

On the ferrule is a lock nut 14, this look nut bein elongated and on one end is screwthreade on the inside to engage the screwthread of the ferrule and also extends for a short distance on the outside of the shaft.

The lock nut is spaced from the shaft and is provided on the inside with a cushion, usually a ring of rubber, which is shown at 15 and which acts as a cushion when a stroke is made with the club so that the thin metal of the shaft is' cushioned to an extent to protect it from breaking.

When a shaft is to be secured to the club head it is screwed into the club head up to the lock nut 14 and then by a sharp partial turn of the lock hat the club head is secured against turning and is tightly fastened on shaft.

CLUB.

1, 1927. Serial No. 216,866.

In the clubs used by I right-hand players it is a left hand thread so that when the club head strikes a ball the force of the blow tends to tighten the club head each time which is a further safe-guard against its becoming loose. In the case of clubs for left-hand players the thread, ofcourse, would bea right-hand thread for the same purpose.

,To tighten the lock nut properly a key is provided which in the form shown comprises a spanner wrench 16, the end 17 of which fits in the hole 17 inthe lock nut. The spanner wrench can be made to fit inv the upper end of the shaft and can be held therein by friction. The top end 18 of the wrench may have a spring lip 19 to co-o erate with the part 20 of the wrench to rictionally engage the sides of the inside of the upper end of the shaft. A button 21 can be secured to the end of the wrench to limit the movement thereof into the shaft struction can be changed without departing.

from the scope of the invention.

I claim 1. A golf club comprising a shaft, a screwthreaded ferrule secured on the end of the shaft, a club head with a screw-threaded recess to receive the ferrule, and a lock nut on the ferrule above to engage theend of the-club head and to. extend over part of the shaft.

2. A golf club comprising a shaft, a screwthreaded ferrule secured on the end of the shaft, a club head with a screw-threaded recess-to receive the ferrule, and a lock nut on the ferrule above to engage the end of the club head and to extend over part of the shaft and a lining of rubber in the nut where it surrounds the shaft.

3. A golf club comprising a thin hollow Qmetal shaft and a head in screw-threaded engagement therewith and an'elastic cushion interposed in the connection to ease the strain onthe shaft where it enters the head when a stroke is made with the club.

4. A golf club comprising a shaft, and a set of heads interchangeable with the shaft, a lock nut to secure the parts in locked en-' gagement and a key for operating the nut, the key fitting into the upper end of the shaft when not in use.

5. A golf club comprising av shaft and a head, means for (letachahly securing them together, a key for operating the securing means, said key fitting in a recess in the end of the shaft and having a button for closing the end of said recess.
